Simplify the expression below: 2w(4w^2-2w) + 3w(-2w^2+8w)

2w(4w^2 - 2w) + 3w(-2w^2 + 8w)

First distribute 2w and 3w(you do this by multiplying them to all values inside the parentheses):

8w^3 - 4w^2 - 6w^3 + 24w^2

Now simplify by adding/subtracting like terms:

8w^3 - 6w^3 = 2w^3
-4w^2 + 24w^2 = 20w^2

So we have:

2w^3 + 20w^2

The reporter forgot to multiply the decimal by 100, making it 25%

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
